These are the questions we hear most when teams build on WalletSuite MPC.
No. Every wallet is self-custodial. You hold the wallet and WalletSuite holds a co-signing share, and both are needed to sign. WalletSuite can never sign alone, so it never has custody of your users’ funds. See Shares & thresholds.
No. There is no moment where a full private key exists on any machine. Each side holds its own share, and a signature is produced jointly without either share ever leaving its owner. One stolen share is useless on its own. It reveals nothing about the key and cannot move funds.
Your funds stay safe and nothing is lost. Signing pauses because both shares are needed to sign. The wallet stays valid, the on-chain balance is untouched, and signing resumes the moment the service is reachable again.
You sign transactions across 84 chains including Ethereum, Base, Bitcoin, Solana, Tron, and more. One wallet works everywhere. See Supported chains for the full list and Signing for the developer flow.
In durable storage you control, never a temp directory, and keep a secure backup. The SDK returns the wallet as an opaque blob and does not persist it, so you pass it back on every operation. Good homes include your database, a KMS or HSM, the user’s device, or a passkey-wrapped envelope. Your secure backup is your recovery. For patterns, see Shares & thresholds.
There is no full private key to export, by design, so there is nothing for a stolen export to drain. For a managed recovery path, see Recovery.
Yes. Your secure backup of the wallet is your recovery: restore it from durable storage and signing resumes. Keep the wallet backed up and out of temp directories. A managed recovery path is available as an opt-in under separate commercial terms. See Recovery.
